Check the active NS records for a domain and see which nameservers are delegated for it.
Use this free NS Record Lookup tool to check which nameservers are currently delegated for a domain. It is useful for troubleshooting domain delegation, verifying nameserver changes, checking whether a registrar update took effect, comparing expected DNS providers with live NS records, and understanding which nameservers are authoritative for a domain before deeper DNS troubleshooting.

Use ns record lookup when you need a fast browser-based result without extra setup. It works well for quick checks, one-off tasks, and routine formatting or calculation work.
NS Record Lookup focuses only on delegated nameservers. DNS Lookup gives a broader overview of multiple record types such as A, MX, TXT, NS, and CNAME. If the main question is "which nameservers are active right now?", the NS tool is the better fit.
NS Record Lookup is better for checking live delegated nameservers. WHOIS Lookup is better for registration context such as registrar and expiration details. If you are troubleshooting delegation, the NS tool is usually more directly useful than WHOIS.
After confirming delegation, use DNS Lookup to inspect live A, MX, TXT, and other records. If you need registrar and expiration context as well, open WHOIS Lookup. If the issue is specifically email-related, the next useful step may be MX Record Lookup.

Actual live NS records
Helpful when the nameservers in your control panel do not seem to match live results.
Input
not a real domain
Output
Invalid domain or no NS records found
The lookup fails if the input is malformed or the domain cannot be resolved.

Nameserver list different from expected provider
Useful for spotting that a domain is still delegated elsewhere.
Fix: NS records only show delegated nameservers. Use DNS Lookup to inspect A, MX, TXT, and other records.
Fix: Always compare the live NS result with the expected registrar configuration, especially during propagation.
Fix: Nameserver changes may take time to propagate depending on registry and caching behavior.
Fix: WHOIS may show nameserver-related data, but NS lookup is better for checking active delegated NS records.
Fix: Make sure the input is a clean domain name without spaces, paths, or unrelated text.
An NS record lookup shows which nameservers are currently delegated for a domain.
NS Record Lookup focuses only on nameserver delegation, while DNS Lookup gives a broader view of multiple DNS record types.
NS Record Lookup is better for active delegated nameservers, while WHOIS Lookup focuses on registration and registrar-related information.
The most common reasons are propagation delay, registry update timing, caching, or a registrar setting that was not fully applied.
Yes. It is one of the best quick checks to confirm whether delegation moved to the new provider.
No. NS records show nameserver delegation, not mail routing or A/AAAA host resolution.
Yes. The nameservers can be correct while other record types such as A, MX, or TXT are still wrong.
It may still be delegated to an old provider, or you may be seeing propagation-related differences.
Yes. If delegation itself is wrong, checking deeper record types may not explain the real problem.
Use DNS Lookup after confirming delegation when you need to inspect the actual DNS records hosted on those nameservers.
